Relocating Apps/Call/Personalize barGeneral

My wife has been playing with my phone and has somehow managed to drag the bottom bar so it is now up the right hand side of the screen - and I want it back to the original position. She doesn't know how she managed it, and I can't seem to find any reference to moving this bar anywhere.

Had the same problem. I hope you've fixed by now. Lol. I just went to settings and /or personalise and loaded another htc skin. Then loaded back to the old one and hey presto, back on the bottom of the screen. Cheers.
